I think you would do well to read Meister Eckhart, who was a great German mystic within the Catholic tradition who will give an antidote for the answers you might find here. Basically he says that if it “feels” like something then it is not God. If it is a vision of a concrete thing, then it is not God. I will leave it to Meister Eckhart to explain this to you if you are interested. But do not believe everything that people will tell you about things like “what it feels like to be with God.” Those how know do not say, and those who say probably do know know.
